l UNIVERSAL JOINT.

Specification of Letters Patent.

Be it. known that I, KARL F. RANGER, acitizen of the United States,residing at Battle Creek, Michigan, have invented certaln new and usefulImprovements in Universal Joints, of which the following is aspecification.

This invention relates to improvements in universal joints.

The main objects of this mvention are:

-First, to provide an improved double universal joint which is verycompact. Second, to provide an improved universal strong and durable.Third, to provide an improved universal joint in which the parts aresimple and economical to produce and easily assembled or disassembled.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplishthe objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly defined and pointed out in the claim.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure 1 is a side elevation of a structure embodying the features of myinvention.

Fig. 2 is a side elevation of the structure shown in Fig. 1, turned. onequarter way Fig. 3 is an end view, looking from the right of Fig. 2.Fig. 4c is a longitudinal line corresponding to section taken on a line4% of Fig. 2. Fig. 5 is a transverse section, taken on a linecorresponding to the lines 55 of Figs. 2 and t, the journal pin beingshown in full line. Fig. 6 is a detail transverse section taken on aline corresponding to line G(& of Figs. 2 and 3.

In the drawings. similar reference characters refer to similar partshroughout the several v ews,rand the sectional views are looking in thedirection of the little arrows at the ends of the section lines.

Referring to the drawing. the shaft members 1 and 2 are forked andprovided with bearings 3 on the arms of the forks. The

provided with oppositely-disposed journals 5, and with holes 6 at-rlghtangles to the journals 5 to receive Patented Aug. 6,1912.

the bearing pins 7 for theshaft members. These bearing pins arepreferably retained by means of the locking pins 8, which are arrangedtransversely through the cross members and the bearing pins, see Figs. 4and 5.

The cross members 4' are by a coupling consisting of a pair of members 9and 10, each having a pair of oppositely-disposed bearings 11 for thejournals 5 on the cross members. These coupling members are preferablyprovided with male and female engaging portions 12 and 13, respectively,see Figs. 4 and 6, which assist in retaining the parts togethen, asecuring bolt let being arranged centrally through the coupling membersand through these engag ing members 12 and 13. The bearings arepreferably provided with bushings 15, as illustrated. The ends of thebearings are preferably provided with caps 16.

' The cross member t is provided with shoulder-like bearings 17 for theshaft members, and similar bearingslS for the members of the coupling.

By thus constructing and arranging the parts, they are economical toproduce and can. be quickly assembled or disassembled.

My improved coupling is very strong and durable, and is also taken intoconsideration that it is a double joint structure. I have illustratedand described the samein detail in the form preferred by me, on accountof the structural simplicity and economy and convenience in assemblingor disassembling of the parts. The same may, however, be very greatlyvvaried in structural details without departing from my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

In a universal joint,- the combination of a pair of forked shaftmembers; a pair of cross members having journals at each end; journalpins for said shaft members arranged transversely through said crossmembers, said cross members being provided with thrust bearing surfacesfor said shaft members; and a coupling for said cross members comprisinga pair of members, having oppositely-disposed bearings for the journalsof said cross members, said cross members being provided with thrustbearsecured together very compact when it is ings for said couplingmembers, said coumy hand and seal in th pling members being providedwith male nesses. v and female engaging portions disposed between saidcross members, and a retaining KARL F. RANGER. [L 3.

' 5 bolt for securing said coupling members to- Witnesses gether,located between said cross members. C. M. RANGER,

In witness whereof, I have hereunto set I L. N. C. RANGER.
